Vertigo is a feeling of movement or spinning when you are still. Benign paroxysmal positional vertigo (BPPV) happens when the vertigo is caused by changes in the position of the head. This might include standing after bending down, turning the head in bed, or extending the neck to look up. People with BPPV can often identify which moves cause the most problems.

The inner ear contains tiny crystals. These crystals can sense movement and help you keep your balance. BPPV occurs because of a shift in location of these crystals or the clumping of these crystals. When this happens, your brain gets signals that you are moving when you are really not moving. This causes the feeling of movement.

In some cases, the cause of BPPV is unknown. In others, it may be caused by:

  • Viral infection
  • Disorders of the inner ear
  • Prolonged immobility of the head
  • Age-related changes to inner ear
